In the editor. I can't think of any reason why timing points should reset the slider velocity multiplier to 1. Timing and slider velocities are two entirely different things. Right now, the only option is to add a green line on top of the red one, which can cause problems in the editor. Also, if the first line needs a different slider velocity (for structure reasons) and the song has an anacrusis (ie objects before the first timing point), then the only way to make it happen is to move the offset back a certain number of measures, which makes the timing incorrect (also, fuck negative offsets). So... Why not add that to red lines ?
